The Ecovessel BOULDER vacuum insulated water bottle is made from premium 18/8 stainless steel and keeps drinks cold up to 74 hours and hot up to 14 hours. The dual-opening lid is easy to grip, has a wide mouth for easy filling, and a soft silicone spout for a comfortable drinking experience. The lid is securely attached to a sturdy carrying strap, so you always know where it is, and the leakproof seal keeps your drinks in the bottle - where they belong. The BOULDER stainless steel water bottle also includes a removable strainer for tea, fruit, and ice cubes. The fitted silicone bumper adds protection against everyday drops. Plus, choosing a reusable water bottle cuts down on single-use plastic consumption. There’s nothing the BOULDER doesn’t offer!
